Hello all,
I’ve the following HTML code along with Javascript file. When I select any option in listbox 1, listbox 2 is populated with associated values. This implementation is more of dependent listboxes.
Please help me out of how to insert ‘ALL’ at the top of options in the listbox2.
Thanks in advance…
