I'm using the marvelous Page Load CustomActions/Row_CustomAction combination to add a feature to the top and bottom of a list page table. But I need a combobox (also known as a select box or a dropdown) as part of the feature and for the life of me I can't figure out how to create one. I can add a button in List Page Page_Render ($this->OtherOptions["action"]->Add), but I don't see a method to add a combobox.
Can it be done, or do I have to use Javascript/Jquery to convert the button into a combobox and populate it client side? My worry is that, if I do that, can List Page Row_CustomAction get the display value of the combobox? How would I do that? Post it to some sort of global variable whenever the combobox changes?
The feature is actually triggered when the user pushes a second button. The idea is the function would read the value of the combo box and apply that value to all the selected rows in Row_CustomAction.
Thanks!
