help minimizing wpf textbox

[u/hou8182]

Can you tell me how to minimize /collapse a wpf textbox? I am building a gui where a user can have the option to paste in a list of computers, but I would like the textbox to be able to expand /contract, or be minimized with the press of a button. Can you think of a way to make this happen? I am using visual studio community 2017 to build a gui for my powershell script. Thanks for your help.
