10 Attribute Priority

What happens when you write more than one th: * attribute in a single tag ? For instance:

Item description here...

We expect that the th: each attribute will be executed before th: text so that we get the desired results, but given the fact that the HTML / XML standards do not matter for the order of the attribute in the tag, the priority mechanism must be set in the attributes themselves to be sure that it will work as expected.

Thus, all Thymeleaf attributes define a numerical value that sets the order in which they are executed in the tag. This order:

Order	Functionality	Attributes
1	Inclusion of fragments	th: insert th: replace
2	Fragment Iteration	th: each
3	Conditional execution	th: if th: unless th: switch th: case
4	Local variable definition	th: object th: with
5	Basic attribute modification	th: attr th: attrprepend th: attrappend
6	Specific attribute modification	th: value th: href th: src ...
7	Text (tag body modification)	th: text th: utext
8	Fragment definition	th: fragment
9	Delete a fragment	th: remove

This priority mechanism means that the above iteration fragment will give exactly the same results if the attribute position is inverted (although it will be slightly less readable):
