The palette frevvo palette offers a rich variety of controls that let you create virtually any form. All controls provide functionality as soon as you drop them into your form and can be customized to suit the form you are designing. The purpose of each control is described below.

...

To validate the content in each input control,  assigns frevvo assigns a default XML schema data type to each control.  The table below shows the default data types for each input control.

...

Text controls allow users to type any text and is are intended for short, one-line entries.

...

Since users typically enter multi-line text into TextArea controls this can pose a challenge if you want to display that text in an html HTML page. For example, you may want to display the entered text in your form's Doc Action display message, in an html HTML formatted email, or in on a web page such as your Confluence wiki. The challenge is caused by the fact that line breaks entered into a TextArea control are represented by a single newline character \n while line breaks in an html HTML context are represented by the html HTML break characters:

<\br>

In order to display the text in a html HTML context you need to replace the \n with the html HTML break characters. See the business rules chapter TextArea newline vs break for a working example.

...

...

The Money control allows users to enter U.S. currency. Users may type commas and a decimal point but will frevvo will not add them to the data automatically. The form also will round all entries to two decimal places. For example, if the user enters 4000, it will display as 4000.00 when the user exits the field.

...

The Number control is used for entering decimal numbers. Users may enter any number of digits after the decimal place.

Selection Controls

 supports frevvo supports five types of selection controls. Selection controls let users choose from a list of options instead of having to enter text.  

...

1. Design Time (Static Options)- Designers enter the options at design time by typing them in the Options property for the chosen selection control. Options entered in this way are static - they will not change at runtime. The controls are discussed below.
2. Web Service (Dynamic Options) - Designers can dynamically populate options at runtime from an external RESTful web service source, such as the frevvo Database Connector. The Dynamic frevvo Dynamic Option feature allows you to do this without code right in the control properties panel. If you prefer, you can also set dynamic options using a business rule. Refer to the Dynamic Options topic for the details.
   

...

You can use the ComboBox to retrieve values from a database and enable a list of possible partial matches.

LDAP frevvo LDAP customers often use the ComboBox control if they have many users/roles configured on their LDAP server. What if the designer wants to pull a list of users or roles from their LDAP server into a form or workflow for user selection? Using a traditional dropdown control is not ideal especially when you have thousands of users to pick from. The ComboBox control allows users to type characters in the ComboBox control that filter the choices to the entered characters and display those that match. You can also type a value that is not in the list. You may limit responses to the available options by selecting Options Value Only (available only for frevvoUsers and frevvoRoles.) Checking Options Value Only is recommended when using the ComboBox value in form routing; allowing a value that is not in the list could result in an invalid task assignment.

Drag/drop the ComboBox from the Palette or import it from schema ComboBoxfrom Schema. When you drag/drop the ComboBox from the Palette, it does not have a Control Type ControlType property. You cannot change the ComboBox to a different control by changing the value in the Control Type dropdown. You must delete the ComboBox and then add the control that you want. 

...

A  Comment property can be used to  provide to provide a text box for additional information when the last option in the selection control is chosen. 

...

This adds a set of checkboxes so users can check one or more. As with the other selection controls, you edit the control’s Options properties to define the number of checkboxes and the specific choices. A Comment property can be used to  provide to provide a text box for additional information when the last option in the selection control is chosen. 

...

Use a T/F (Boolean) control in your form for situations where the values will only be Yes or No. For Example: example, The image shows a T/F control in the Preferences section of a company Travel Request. The label for this field has been changed to Non-Smoking Hotel Room. The employee filling out the request checks the box if they prefer a Non Smoking room.

...

The control options default to "true=Yes" and "false=No". When you drag the control from the palette, only the "Yes" option will be visible. You can change the option labels from Yes and No to whatever you want. However, changes to the label for false are irrelevant as it will they will never be visible on the form. The option values cannot be changed and will always stay as true and false. Blank labels for options are not allowed. Checking the “Yes” checkbox of the Boolean control results in a true value in the XML document.

...

The upload control contains special properties to control the max attachment size allowed (in bytes), the min and max number of attachments MaxSize, the Min/MaxNumberof Attachments to accept per form submission and to allow the form designer to specify restrictions RestrictedContentTypesandOtherMime/Ext on the types of files allowed to be uploaded to the control/form. When a user uploads content to an upload control with a content filter applied,  will  frevvo will check the upload against the filter and if there is no match, reject the upload with an error message.

Attachments are viewable in the Submissions Repository. You can configure your form's Doc Action property to send attachments to a URL endpoint (ex: servlet) that can save the attachments locally within your company.

The File Name Changingthefilenameofanuploadedattachmentintheform/flowsubmission property allows designers to specify a naming convention for the attachment in the form/workflow submission.

...

You can specify the minimum and maximum number of attachments that can be uploaded to your form using the Min # and the Max # properties. Setting the min and max values to 0 or if the maximum # field is left empty means an unlimited number of files can be uploaded. Setting the min # to a value greater than zero makes the field required. Set the min # to 1 to ensure that the user uploads at least one attachment to your form. Use the max # for the maximum attachments allowed. Clicking on Add Files will not display the upload lightbox when the maximum # of attachments have been uploaded. No further uploads will be allowed. Setting the Max # to 1 disables the multiMulti-selectFileUpload feature. See below for more information.

...

The Message Control has a Rich Text EditorRichTextEdit which allows you to enter and format text easily. If your prefer, you can type the message content into the Message property, and add your own HTML for formatting.

...

1. Drag a Message control from the palette and drop it into your form/workflow. Click on it, and look at the property panel to the left.
2. Click the Rich Text toggle switch to turn the Rich Text Editor on.  will remember the RTE mode you set for each control the next time you edit the form/workflow.
3. When you toggle it on, the message property will be replaced with a link to "Edit with rich text editor." Click the link to open the RTE Editor window. You can also click the red pencil icon  on the control to open the RTE Editor window.
4. The editor consists of an editing area for entering text EnteringText and an icon in the top left that shows/hides the editor toolbar and menus.
   

...

...

When you drop a Message Control in a Table and turn the Rich Text Editor on, the red pencil icon will not be visible on the control. Click the "Edit with rich text" link in the properties panel to open the RTE Editor window.

Message Control in a Repeat

You can drag and drop a Message control from the palette into a repeat or into a section that then gets dropped into a repeat. You can write Rules affecting the Message controls in repeats. Message controls in Repeats can contain templates. Repeat controls containing Message controls can be converted to Tables. Refer to the Control Type property for the details. 

Horizontal Layout using the Message Control

Let's say you wanted to modify a section of your form to reflect a horizontal layout. One approach would be to use the Table and Radio ControlsHorizontalLayoutusingtheTableControl.  Another alternative is to use three Message controls and three Radio controls. Follow these steps: 

1. Drag and drop a Panel onto the designer canvas.  
2. Drop Message controls into the panel for the user instruction and the labels Fellowship announcements, Conferences and workshops and Other major news and events. Select None in the Message Control Type field.
   
3. Click on the Style tab. Set the width of the Message Controls to half the size of the panel.
4. Place 3 Radio controls with Yes/No options to the right of the Message Controls for the 3 choices. Check the Hide Label property for each.
   
   1. Click the Style tab and enter 50% in the Item Width property
5. You may have to insert a single line break HTML tag in the Message property to align the Message Control text with the Yes/No options of the Radio Control.

Here is what the form looks like in the Forms Designer:

 Here is how the form looks in use mode:

The message informs the designer what the configured limits are so they can take corrective action.

Centering Images using the Message Control

You can add a Message control on the left side of an image uploaded to your form to center the image. Message controls can be set to an empty string. Delete the default text in the message control. Change its Message Type to None. This will add a blank area on the left of that image and move it into the center. Click the Style tab if you need to modify the width of the message control.

Trigger Control

The trigger control adds a button to your form and is used in conjunction with rules. If your form does not have rules you will not need the trigger control. If your form does have rules, see Triggers & Dynamic Options for details on how to use trigger controls and examples of when you might want to use them.

A table/grid layout in a form is a useful space saving technique. The use of panels to create columns can be replaced by using the table control. This control makes table/grid form layout easy by allowing you to create a table with user designated columns and rows. You can edit the table name, column names, drag and drop new controls from the palette, and set the widths of the columns. You can control the number of rows in the table by clicking on Add/Remove icons that appear to the left of the first column in the table. You can hide the delete icon to eliminate deletion of a row in a table rows using the deletable property or allow only a certain number of items based on user input using a business rule. You can also use business rules for computed values, enabling/disabling fields, showing/hiding fields etc. When tabbing through a form, use Shift-Right arrow or click on a table cell to begin tabbing into a table. Tables are always 12 columns wide when you drag/drop it from the palette. Table controls do not have an identifying icon like 1062647100 Panels and 1062647100 Repeats do.

When you drag the table control into your form, the control will have three rows and three columns. The Table is assigned a default name i.e.Table95. The columns will display the default names of col 0, col 1 and col 2 respectively. The  and   icons will display for each row in the table, allowing addition and deletion of rows. Deleting all the rows will result in a table with one row. Notice the name of each tables column is unique.

...

Other controls can be dragged into the table (Dropdown, Radio, Checkbox, Message, Text, Text area, Date, Email, Money, Phone, Quantity, Number, T/F). Drag the control from the palette. The new control will appear as a column positioned to the right of the column where it is dropped. For Example, a date control can be dragged from the palette and dropped over the Description of Expense column. Adjust the column widths ColumnWidths in the table if necessary. Notice that the cells in the added control column do not have the Required property checked. The form designer must set the Required property as appropriate for newly dragged columns. Help icons for a column with a label that has multiple lines may not align properly. Adjust the column widths if possible. 

...

Dragging a message control from the palette and dropping it into a table will provide a column in the table that can be used to label the table rows. Move the message column to the desired position. The text of the message control of each cell in that column can then be set as desired.  The days of the week in the Day column of the Timesheet form shown below is an example of using the message control with modified text for row labels. Remember the Rich Text Editor MessageControl is available for easy creation of your Message control content.

...

1. Drag a Table control from the palette and drop it on the designer canvas.
2. Drag a Message control from the palette and drop it into the table to create a column. Click on the column header and check the Hide Label property on the Settings tab. Delete unwanted columns.
3. Modify the rows of the Message control column for the labels. The Rich Text Editor MessageControl is available for easy creation of your Message control content.
4. Drag a Radio control from the palette to the canvas. 
   1. Set up the Yes/No options for the Radio Control.
   2. Specify the item width on the Style tab so that the options display horizontally.
5. Drop the Radio Control into the table to make a second column. 
   1. Click on the column header and check the Hide Label property.
6. This is what the table will look like in Use mode.

You can have multiple controls inside a repeat. To do this, first add your controls to a section control, and then drag the section into the repeat control. Only one section is allowed inside a Repeat control. Sections inside repeats will not have the Securities Properties Tab SecurityProperties, since signatures are not supported in Repeats.

...

Let's try another example. You are designing a form for mobile devices. You drag and drop one control on the form. Now you want to add the PageBreak control and then add other controls below it. You cannot drop the PageBreak below any control so you will have to add the other controls first and then drop the PageBreak control where you want it. Once you add more than one control to the form, you can drop controls from the palette or the form above or below the page break. You can drag and drop the PageBreak itself anywhere at the root of the form. The PageBreak control should not be dropped inside sections, panels, tables or repeat group controls. The only exception is the Tab control. See below PageBreaksinaTabControl for the details.
