LDAP customers may 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 flow for user selection? Using a traditional dropdown control is not ideal especially when you have thousands of users to pick from. Dropdown control options are confined to a predefined list and maybe limited by the default max result size of an LDAP query. The Combobox control allows users to pick from a predefined list of values or type a value that is not in the list.
The Combobox is used internally for functions such as creating the Access Control List.
...
Users can typeahead to narrow the choices based on the letters entered. User ids and roles are case sensitive so remember to use the correct case when typing.
The combobox supports the ability to specify single or multiple values. Simply check the single value checkbox if you want to limit the choice to one value.

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. It is important to note changes to the label for false are irrelevant as it 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.

Select the content types you want to allow by checking the associated check box in the Restricted Content Types field. The choices are: pdf, MS Word, MS Excel, MS PowerPoint, MS Access, gif, jpeg, png, tiff, rtf, tar, zip, gzip, xml and bmp. will map the content types that you choose to one or more mime types. Content type filtering will be enabled for the extensions selected. For example, the image shows an upload control in a form that will only allow files with .jpeg, .pdf and .png extensions. This list can be expanded for customers using in-house by modifying the context parameter: frevvo.upload.file.types in the web.xml file. See Installation Tasks for the details.
An easier way to add extensions or other mime types for filtering can be accomplished via the Other Mime/Ext field. You can use this field to restrict uploads to a mime type or file extension that is not included in the subset of the most common file content types provided by . Enter one or more extensions (of any length) or mime types, separated by a space, to enable extension and additional mime type filtering. An upload matches on an extension if it's name ends in a period followed by one of the extensions. The comparison is case insensitive. Likewise, an upload matches on mime type if it's mime type matches one of the additional mime types entered. For example, the extensions, txt and htm, shown in the Other Mime/Ext field in the image above, restricts uploaded files to ones that have .jpeg, .png, .pdf, .txt and .htm extensions.
...
The user will see error messages if upload filtering is applied and the uploaded content types do not match. The error message, shown below, will be displayed if content type only filtering or both content type and extension/mime filtering has been applied and the uploaded content does not match either restriction. For instance, uploading a file with a .jpeg extension will not match the selected content type choices or the .docx file extension listed in the Other Mime/Ext field as shown in the Upload Control Property Pane image:

Let's say you wanted to modify a section of your form to reflect a horizontal layout as shown in the image.
One approach would be to use the Table and Radio Controls. Another alternative is to use a Message control in conjunction with a Radio control to accomplish this. Follow these steps:
- Use a Message control for the labels Fellowship announcements, Conferences and workshops and Other major news and events
- Place the Radio control with options to its right.
- Check the Hide Label property of the radio control.
- Here is what the form looks like in Use mode:
You can use the Message control to center images uploaded to your form. Click here for the details.
...
Choose images that fit sensibly in your form before you upload it. The “regular” form size is 600px. You can resize an uploaded image by selecting the image control in the designer, clicking on the style tab in the properties panel and setting the width.
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. Replace the default text in the message control with one or more spaces. 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.
Video Control
This lets you include video files in your form and works the same way as the image control. The control supports .SWF files and other video file formats that are supported by your browser. This control does not allow the designer to resize the video area. If your video is already hosted on another web service it is often best to embed your video into your form using a message control and adding the following html code to that control as shown below:
