Hi Muhammad Bilal,

Have you considered adding and removing options from the field customisation screen?

Hi Ben,

Thanks for your response,

i have already looked this solution. but my issue is, i want to remove all selected and unselected options and add new ones. Options can be removed but the selected values still remain in the Multiselect Input, when i click on Multiselect, it shows nothing in the drop-down but after closing the drop down the previously selected values appear again there.

It's worth looking at https://community.dynamics.com/crm/b/vikranthpandirihowtoseries/archive/2017/11/04/dynamics-365-v9-0-set-multi-select-option-set-values-using-jscript for how to add and remove values in a multi-select optionset.

Note that all the examples use formcontext rather than Xrm.Page as multi-select optionsets are new functionality and Xrm.Page was deprecated...
