Detect whether children are defined

[mschoettle]

I wanted to build a component where the children are optional and that depending on the presence of children the output is different.

I tried to detect it via children|length but since it also contains whitespace (see example below) that did not work.

    {% #menu title="Test" %}
    {% /menu %}

In this example children|length returns a number > 0 since there is whitespace.

    {% #menu title="Test" %}{% /menu %}

Here children|length returns 0.

Is this possible at all to detect this?

Have you tried children.strip|length?
