"Select All/multiple select" Checkbox/Option for List field

[shilpidev10]

Hi All, 

I'm looking to see if there is away to add 'select all/Multiple select' checkboxes for a List type field data?

Thank you all in advance!

Hi,

Out of the box, a List type field does not support “Select All” or checkbox-style multi-select. The checkboxes you see in list views are only for record selection in the UI, not for field values.

Use a List Collector instead of a List field. It supports multi-selection and provides a built-in way to move all records (>>), which effectively works like “Select All”.

If you strictly need a “Select All” option, you can:

• Add a checkbox variable (e.g., Select All)
• Use a Catalog Client Script to populate all values into the List Collector when checked

But this is a customization and only works in Catalog/Portal, not standard list fields.

There’s no OOB way to add “Select All” inside a glide_list field, so the fix is to replace the default slushbucket with your own UI that supports checkboxes. Create a UI Page / Service Portal widget / Workspace component that shows the same records in a table with checkboxes and a “Select All” option, then on submit collect all selected sys_ids and set them into your list field (comma-separated) using a client script or server call. Finally, hide the original list field on the form and use your custom component instead. This way users get proper multi-select + select-all, while the data still saves correctly in the list field.
