preserve-all-blank
From Documentation
Property: preserve-all-blank
Applicable: globally in zk.xml via <library-property> not as <custom-attribute>
Default: true [Since 8.0.0]
This property control how the zul parser interpret whitespaces (such as line breaks and spaces) between zul elements.
Considering this source:
<label value="text" />
<a>link</a>
If preserve-all-blank is true, the result will be:
text link
If preserve-all-blank is false, the result will be:
textlink
Note: the same element will not cause whitespace if no whitespace exists in the source.
Considering the following source:
<label value="text" /><a>link</a>
will always return: textlink, since no whitespace exists between the label and the link element.
