In general, you would hide all toolbars except your custom toolbar, using `slicer.util.setToolbarsVisible(False, [myToolbar1, myToolbar2])`. You can add your custom toolbar and actions to it using standard Qt calls.

Can I hide certain widgets like(marksups) in the built-in toolbar,without hiding the whole toolbar I just want to hide some of them?

This is all just standard Qt API, so you should find answers by googling `qt hide toolbar button`. If you have any specific issue then let us know.

This would also be part of standard Qt API. Widgets have children and parents. So you will need to familiarize yourself with [https://doc.qt.io/qt-5/qobject.html#findChild](https://doc.qt.io/qt-5/qobject.html#findChild) and [https://doc.qt.io/qt-5/qobject.html#findChildren](https://doc.qt.io/qt-5/qobject.html#findChildren) type calls for finding various Qt objects through the application.

</div>

```auto
import slicer

mainToolBar = slicer.util.findChild(slicer.util.mainWindow(), 'ModuleToolBar')

allActions = mainToolBar.actions()

for action in allActions:
    if action.text == 'Markups':
        actionWidget = mainToolBar.widgetForAction(action)
        if actionWidget:
            actionWidget.setVisible(False)
            print('success')

```

I use these codes to hide 'Markups" in toolbar. It does not work. What is wrong?
