I need to create a cascading. multi-select list box on a Submission - that has "select check boxes" associated with each option, and a "select all" button.
I have explored two solutions, both of which don't work.
I know that I could set the data type to List - String, and then multi-select becomes a standard option (with a "select all" option as well). But the problem with that standard solution is that it does not allow for cascading based on another fields in the Submission Form.
I also know that I could use a Cascading List Box, together with the following JS code:
/* "fieldName" is the variable name for the listbox type form element field. */
var fieldName = "InsertRecordCompany";
But the problem with that solution is that the list box does not have "checkboxes" on the side, nor a "select all" button. This makes that solution clumsy for users.
Can you help me implement what I need - a cascading. multi-select list box on a Submission - that has "select check boxes" associated with each option, and a "select all" button
