I have a lookup which options should be filtered by 1 (or more) other fields, that the user enters. So this has to be dynamically.
Easier Usecase:
there is a field “PageCount” and a Lookup with Pages (01,02,03, …). If the user inputs PageCount 8 , the lookup should show only the pages from 01 to 08.
Advanced UseCase:
There are 3 fields - Profitcenter, Datefrom and Dateto:
The Lookup field should show all options of this profitcenter, where datefrom and dateto are within the lookuptables validfrom and validto timespan.
That should not the issue. You may simply change the control type under Fields setup, for example, from Select to Textbox.
As you can see from screenshot below, after typing one or some characters in Trademark field, system will display the suggested option from Parent field, and after selecting it, the Child field (Model) will display the corresponding options as expected.
