how to filter previous selected row, prevent double input on list page？
You description is too brief, you better elaborate so other users can try to help.
in phpmaker 2024 how to data that has been selected by the User in the Combobox located in the first row (for example), should not be selected again in the Combobox located in the row below it. And so on until the other rows in the Detail section.
I assume you are using Grid-Add/Edit. You may use Client Side Events and add “change” event to check other comboboxes of the same field (select based on data-field attribute) in the form.
