Hi all,

I have a situation where I need to hide or show an option in a select1 based on a value of another node. Whats the best approach to doing this?

At the moment I am using this:

<html xmlns:xf="http://www.w3.org/2002/xforms" xmlns:ev="http://www.w3.org/2001/xml-events">
        <title>Test XForm</title>
            <xf:instance id="inst">
            <xf:instance id="form_data">
            <xf:bind id="test" nodeset="/test"/>
            <xf:bind id="select" nodeset="instance('form_data')/select/value"/>
            <xf:bind nodeset="instance('form_data')/select/item[3]" relevant="instance('inst') = 1"/>
        <xf:input bind="test">
        <xf:select1 bind="select">
            <xf:itemset nodeset="instance('form_data')/select/item">
                <xf:label ref="label"/>
                <xf:value ref="value"/>

With the Novell XForms plugin the option is greyed out when not applicable, but you can still select the option. Formsplayer doesn't recognise the item is not relevant.

I'm looking for the most elegant way to achieve this.
