Hi, I’m wanting to link to a lightbox from a button which will ideally have a contact form in it when someone wants to make an enquiry. Can I do this in BB?
Hey Tina,
Welcome to the BB forums! 
Unfortunately, this isn’t possible with BB out of the box. You can use custom HTML via our HTML module to create the button as well as the lightbox effect from scratch. If you’re using the BB theme, you can just use Bootstrap elements to generate your button as well as the modal popup. Check the links below for more info.

You can also try using a 3rd party plugin which generates the popup. I’ve used Popup Maker before and it works fine with BB’s Button module.

Hope this helps, and let us know if we can assist further!
