# Build a Sticky Menu

To make a menu sticky, you need to put the menu and all contents in a container (site wrapper) along with making the following changes to the menu settings:

Layout > Position set to Sticky.

Layout > Z-Index > Custom set to 100.

Layout > Type > Uniform > Inset 0.

Watch the following tutorial to see how to build a Sticky Menu, along with adding a drop shadow and frosted glass effect.
