Radio Button Selection for Multifield - aem

Question

I need an identifier in tabs such that author can specify which tab will open at page load Below is my dialog.xml.
<items jcr:primaryType="cq:WidgetCollection">
<typeconfigs
jcr:primaryType="cq:Widget"
fieldLabel="Accordion"
name="./options"
xtype="customconfigmultifield">
<fieldConfigs jcr:primaryType="cq:WidgetCollection">
<option
jcr:primaryType="cq:Widget"
hidden="{Boolean}true"
name="option_name"
xtype="textfield"/>
<optionval
jcr:primaryType="cq:Widget"
allowBlank="{Boolean}false"
fieldLabel="Title"
maxLength="{Long}60"
name="optionval"
xtype="textfield"/>
<openaccordion
jcr:primaryType="cq:Widget"
name="selectaccordion"
type="radio"
xtype="selection">
<options jcr:primaryType="cq:WidgetCollection">
<one
jcr:primaryType="nt:unstructured"
text="Open at Page Load"
value="in"/>
</options>
</openaccordion>
</fieldConfigs>
<limit
jcr:primaryType="nt:unstructured"
maxVal="{Long}15"/>
</typeconfigs>
</items>
But now i am not getting the behavior of radio button, means i can tick all radio buttons inside each tab that i add via dialog. Any idea how can i make that switch possible. Thanks

Answer 1

The radio button, as defined in your current structure needs two options, and the value of the field will toggle between the two options.In case you just want to show one option, I'd recommend using a checkbox.
I've tried to answer your question by assuming you decide to go ahead with a checkbox (which has two states, true and false). In case you decide to add a second radio button, you can change the values of true and false to the values that you have defined; (one of which is in)
What you are looking for is a set of custom listeners that
i) iterate through each multifield item, checking the value of <openAccordion> of the currently clicked multifield item.
ii) Set it to true for the current multifield item
iii) Set the value of <openAccordion> to false for all other multifield items.
The event that you'd require is selectionchanged.
Once you verify that the properties are getting set correctly, all you need is another listener that triggers on the loadcontent event, that looks for the multifield item with the value of <openAccordion> as true and displays that tab, hiding the rest.
As an aside, in my opinion, you might want to restructure your dialog, something similiar to what #Mathew posted in his comment.
