Add checkbox to options in selectize js

Question

Can I add a flag to the parameter renderers so that users can select and deselect an item by clicking on this flag.

I managed to add a checkbox by adding

<input type = "checkbox"> 

for rendering parameters. But I don't know how to handle the click function and add the selected value to the header. I tried the remove_button plugin. But that is not what I am looking for.

Thanks in advance
