Drop Down

A drop-down control renders to a standard HTML <select /> tag containing <option /> tags. You can populate the drop-down from a data source or define a static list.



Add a Drop Down


Properties

  1. Options

    Specify a list of options to display in the control. It can be generated from a static list or from data. When populating the Options from a connector or file, use the Field Mapping Editor found in the Property Grid (seen circled in red below) to assign the Text and the Value of the items.
  2. Hint

    Some placeholder text that will show when the drop down is empty. This value is not saved if no other value is entered.
  3. Read-only

    Set to True if you want the control to display as read-only (value can't be changed) on the page.
  4. Selected Value

    This value will be shown in the drop down when the field loads.
  5. Validations

    Some validations that can be applied to the drop-down.
  6. Visible

    Set to False if you don't want this control to render on the page and be visible to the user.

Assigning data to a DropDown

Example:

To display a DropDown list containing option values retrieved by a SQL query:

  1. Use an appropriate Event, e.g. Load (page) or Click (button) to which a SetValue action can be added.
  2. Add a SetValue action that populates the DropDown options with each returned value.
