Dear JS Experts,
Can anyone provide a solution to this ?
We use DHTMLX and there is a dropdown filter. We use cookies to save the result. When someone filters by First Name, you get the first name list and when you reload, the list remains as First Name list. However, the dropdown shows as blank.
We would like to store the value of the filter in the drop down instead of showing as a blank field(resetting) eg: Filter by First Name > First Name list shown > Reload page > First Name list shown and Dropdown to show First Name.
Ideally a pure javascript solution is needed. Any help is much appreciated.
