# Working with the Demo Browser

{% embed url="<https://youtu.be/20ub4JfWG5w>" %}

The Wisej.NET Demo Browser contains an example of every control within Wisej.NET. You can check it out [here](https://wisej-demobrowser.azurewebsites.net/).

Let's look at the Demo Browser code for [listbox](https://docs.wisej.com/docs/controls/lists/listbox). Listbox presents a collection of items, either as plain text or bound data, enabling users to choose a single entry or multiple selections.

First open the Demo Browser and search for "listbox" using the search bar on the left hand side.

Then, click on the code link to pull up the source code for the listbox example.

It should look like this:<br>

We can see that the code is in the "Demos\Editors\Wisej.DemoBrowser.ListBox" folder

Clone the Demo Browser repository off of github. If you are unfamiliar with cloning a repository, check out [this tutorial](https://docs.github.com/en/repositories/creating-and-managing-repositories/cloning-a-repository). Another way to clone a repository is through GitHub desktop, which you can download [here.](https://desktop.github.com/download/) [This](https://docs.github.com/en/desktop/adding-and-cloning-repositories/cloning-a-repository-from-github-to-github-desktop) is a tutorial for cloning a repository with GitHub desktop.

Note that in order to open the designer you will need to compile the project first.
