Form Elements

The heart of the form are the different form elements. They can be configured in the properties panel for each page. The form elements by default split a line into blocks of the same width.

The form elements can have the following properties:

  • A Name - only used for the display inside the properties panel array.
  • A Label - the text displayed above or next to the form element.
  • Hidden - remove the form element from the form if the qlik expression evaluates to true or -1
  • Disabled - disable but show the form element if the qlik expression evaluates to true or -1
  • Save if hidden - if the value of the form element will be saved even if the form element is hidden
  • Data options
  • Validation options

And can be styled:

  • Margin Bottom - the margin below the form element.
  • Placeholder - the placeholder text displayed in the form element.
  • Horizontal Order - The label and form element are placed next to each other in one line.
  • Alignment - align the form element label to the left, right or center.
  • Required Star - display a red required star next to the Label.
  • Border Color - change the border color of this form element.

Multiple Selections allows to select multiple options and save them as an array. Most of the time you will join the array via formatting to save the field in the db.

Selection independence & dependent selections (object)

The values are dependent on the selections made in contrast to the dropdown label expression which are selection independent. To avoid - symbols after selecting a value (and errors while selecting) in the dropdown you can use Set Expressions.

Simple:

Value:
Only({1}Num)

Label: 
Num

With filter:

Value:
=only({<job_id={'$(=GetFieldSelections(job_id))'},article_id>}article_desc)

Label:
=aggr(only({<job_id={'$(=GetFieldSelections(job_id))'},article_id>}article_id),article_id)
