Hi everybody,

I need to put units symbol with superscript/subscript into the combo box

but the following syntax:

<h:selectOneMenu >

    <f:selectItem itemLabel="ng.l<SUP>-1</SUP>" />

    <f:selectItem itemLabel="µg.l<SUP>-1</SUP>" />

    <f:selectItem itemLabel="mg.l<SUP>-1</SUP>" />

</h:selectOneMenu>

raise the following error:

The value of attribute "itemLabel" associated with an element type "null" must not contain the '<' character.

The tags &sup1; , &sup2; and &sub3 are not useful.

Any idea to have superscript/subscript possibility in combo box?

Regards,

Anton

Hi,

you cannot put "<" inside XML attributes, that doesn't work even in normal HTML. You'll have to use entities and then turn off escaping in <f:selectItem>:

<f:selectItem itemEscaped="false" itemLabel="ng.l&lt;SUP&gt;-1&lt;/SUP&gt;" />

unfortunately this doesn't work for the native select - its appearance is based on the OS and it doesn't support HTML and <rich:select> will always escape the labels. On the other hand it works for checkboxes and radioboxes.
