Adds a content area to a source using Flux FlexForms

Only works to insert a single content area into your element. To insert multiple content areas, use instead a full flux:grid with your desired row and column structure; each column then becomes a content area.

Using flux:grid after this ViewHelper in the same flux:form will overwrite this ViewHelper.

Using this ViewHelper after flux:grid will cause this ViewHelper to be ignored.

Example of difference

<flux:form id="myform">
    <!-- Creates a basic Grid with one row and one column, names
         the column "mycontent" and makes Flux use this Grid -->
    <flux:content name="mycontent" />
    <!-- Additional flux:content tags are completely ignored -->
</flux:form>

<flux:form id="myform">
    <!-- Creates a full, multi-column/row Grid -->
    <flux:grid>
        <flux:grid.row>
            <flux:grid.column name="mycontentA" />
            <flux:grid.column name="mycontentB" />
        </flux:grid.row>
        <flux:grid.row>
            <flux:grid.column name="mycontentC" colspan="2" />
        </flux:grid.row>
    </flux:grid>
    <!-- No use of flux:content is possible after this point -->
</flux:form>
