Sticky button which opens modal dialog

[superdisc]

I am looking to have some sticky button on side which opens a modal dialog upon click. I am planning to use this to provide search box. So, all my search criteria will reside in this modal which will be opened when someone clicks on this sticky button.

You can just create a button and give position: sticky, and add modal functionality just like the example in getbootstrap modal page.
