New Content Element Wizard customization

Per default, all Mask Content Elements are grouped in "Mask Elements". If you want to group your elements in different tabs, you can do this by overriding page TsConfig. Unfortunately, Mask doesn't provide a proper API for this, so it looks a little tricky to do. You can also use this example to simply change the label of the Mask group. See the comments in the code.

mod.wizards.newContentElement.wizardItems {
    # Create new custom group
    myOtherGroup {
        header = My other Group
        after = mask
        # Copy config of Mask elements
        elements.mask_element_1 < mod.wizards.newContentElement.wizardItems.mask.elements.mask_element_1
        elements.mask_element_2 < mod.wizards.newContentElement.wizardItems.mask.elements.mask_element_2
        elements.mask_element_3 < mod.wizards.newContentElement.wizardItems.mask.elements.mask_element_3
        # Add to show list
        show = mask_element_1,mask_element_2,mask_element_3

    mask {
        # Override title of the Mask group
        header = My Elements
        before = common
        # Remove all elements, which shouldn't be here.
        elements.mask_element_1 >
        elements.mask_element_2 >
        elements.mask_element_3 >
