I have to use the HTML 5 data attribute in Tiny MCE, but the editor always clear them, as it's not an attribute known by the default valid_elements configuration.
So I have 2 problems here:
- the data attribute is dynamic ( it could be data-options, data-test, data-foo, etc... ) So I would need a wildcard value or something.
- I want to allow the data attribute for all tags.
So far, I've tried:
extended_valid_elements : '@[id|class|title|style|data-options]',
And:
extended_valid_elements : '*[id|class|title|style|data*]',
But it doesn't work :(

extended_valid_elements is not the best choice here.
Hava a look at the valid_elements setting. Here is an example
// The valid_elements option defines which elements will remain in the edited text when the editor saves.
valid_elements: "@[id|class|title|style|data-options|data*]," +
"a[name|href|target|title]," +
"#p,-ol,-ul,-li,br,img[src|height|width],-b,-i,-u," +
"-span[data-mce-type],hr",
I am using:
extended_valid_elements: "+@[data-options]"
and it works for me. (TinyMCE 4.3.11. Notice the + sign?)
