The 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.

Input Controls

Input controls allow users to enter data (text, dates, numbers, etc.) into your form and automatically prevent them from entering the wrong data types. For example, if users enter letters into a number control, your form will display an error message and form submission is prevented until valid data is supplied. This validation happens automatically; you do not have to do anything special. The purpose of each input control is described below.

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

Input Control	XML Schema Type

Input Control	XML Schema Type
Text	xsd:string
Date	xsd:date
EMail	types:emailType, an xsd:string restriction pattern defined in types.xsd.
Money	types:number, an xsd:double restriction defined in types.xsd.
Phone	types:phoneType, an xsd:string restriction pattern defined in types.xsd.
Quantity	xsd:integer
Number	types:number, an xsd:double restriction defined in types.xsd.
T/F	xsd:boolean

The explanations below describe the controls generically—before you edit them to impose additional restrictions or define behavior specific to the form you’re creating. Refer to Setting Properties for the information.

Text

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

TextArea

The TextArea control lets users type any text and is intended for longer, multi-line submissions. Scroll bars appear as needed to accommodate the text entered. This control has a # of Rows property that controls the default number of lines visible in the input area. The TextArea control is the only input control that does not have a decorator.

In HTML there is no way to set a maxLength on a TextArea control which is why the TextArea control does not have the maxlength property like the text control. If you need a maxlength, it's best to either choose the text control, or this can be accomplished via a business rule. See the Business Rule for TextArea Max Length.

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 page. For example, you may want to display the entered text in your form's Doc Action display message, in an 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 context are represented by the HTML break characters:

<\br>

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

Do not select a TextArea field as a Searchable Field if the amount of text stored in the field is greater than 32k.

Date, Time, and Date/Time Controls

The date control allows the user to enter a date, time, or date/time combo. The designer can choose from a variety of formats for each type.

Designers can add a date picker via the Style Properties tab.

The Date control denotes a day and has no dependencies on time zone.
The Time control denotes the time of the day and has no dependencies on time zones or offsets. It will not shift based on whether or not Daylight Savings Time is observed in a time zone.
The Date/Time control relies on the time zone of the browser. The time portion will be calculated based on the date and whether or not Daylight Savings Time is observed in that time zone. The Date/Time control type is meant to represent a point in time, so certain functions in the Visual Rule Builder (year, month, day, hour, minute) are not available on this control type.

If the form cannot infer the browser time zone, the Date/Time control will display in UTC.

For example, the time 5:00 PM is entered into a Time control and the date 2/4/2020 plus 5:00 PM into a Date/Time control by a user located in the America/New_York (Eastern Standard Time). When the submission is viewed in the EST time zone, the Time Control displays 5:00 PM. This value will not change. The time portion of the Date/Time control also displays 5:00 PM, because it takes on the timezone of the browser (EST) and it is not further adjusted because Daylight Savings Time is not observed in EST on February 4th.

If the submission is viewed in Tijuana (Pacific Standard Time), the Time Control will display 5:00 PM as it did in EST, since it has no dependency on time zone. However, the Time portion of the Date/Time control will show 2:00 PM because it will be adjusted by the browser time zone to PST.

Business Rules can be applied to the Date/Time control in all variations. See the Rules Examples chapter containing numerous examples.
