Making parent template fragments optional #248
Description
I have a base template that drives multiple child pages. These pages all share a common header section, but then there are two sections just below that header that may or may not be required in the child.
<div class="header-container">
<div class="common-header">
...
</div>
<div class="part1" layout:fragment="optional-1">Optional 1</div>
<div class="part2" layout:fragment="optional-2">Optional 2</div>
</div>
If my child template does not have a layout:fragment called "optional-1", then I want the div with class "part1" to not be present in the output. So:
<div class="part2" layout:fragment="optional-2">This from the child template</div>
Should result in:
<div class="header-container">
<div class="common-header">
...
</div>
<div class="part2">This from the child template</div>
</div>
... with the "Optional 1" div completely removed.
The only way I can get this to work is to add a th:remove="all" to the base template, and a corresponding th:remove="none" to all of the child templates (because th:remove="all" without the corresponding "none" in the child template blows away the replaced tag completely)
Firstly, am I missing something obvious?
Secondly, am I weird for finding the need to add an effective manual override in all the child templates feels wrong and inefficient?
