How to hide questions based on specific selections

[reza1921]

Hi all,

I am creating a catalog item that has a select box with some choices (questions). For example lucky_hs and hifi_gs.

There is another select box right after the one above with specific choices (questions). I am trying to show certain questions in the second select box based off the selection in the first one? Is that possible? I cant seem to add a UI policy action to the variable questions, just the variable itself.

Thanks

You can write a catalog client script and use the g_form.removeOption(). This will solve your query.

UI policies can help only in mandatory,visibility and read-only of the variable not to their options

 g_form.removeOption()

Hello @reza1921 ,

You can create On Change Catalog Client Script on one variable for the catalog item and add the given script as shown in below snapshot -

function onChange(control, oldValue, newValue, isLoading) {
   if (newValue == '') {
      return;
   }

   //Type appropriate comment here, and begin script below

   if(newValue == '1'){
   alert(newValue);
      g_form.clearOptions('field_b_depends_on_field_a');
      g_form.addOption('field_b_depends_on_field_a','A','A');
      g_form.addOption('field_b_depends_on_field_a','B','B');

   } else if(newValue == '2'){
      g_form.clearOptions('field_b_depends_on_field_a');
      g_form.addOption('field_b_depends_on_field_a','A','A');
      g_form.addOption('field_b_depends_on_field_a','C','C');
   }
   //Please replace the variable names and choices 
}

I have tried it in my PDI and it is working for me.

Hi @reza1921 

Below post could be helpful :

Instead of having static choices for the second select box, you can make use of g_form.addOption() and g_form.removeOption() method to add or remove the choices based on selection of the first select box in an On-Change Catalog Client Script.

Thanks and Regards
