Disable dynamic Select option based on condition

[famousmag]

Thanks for your input @ben,

My problem is on the select’s option setup ( dmx-bind:disabled). What condition should I use in order to check if the selectedValue of my select is disabled if its value exists in the prod_vars data store…

<select id="selectVars" class="form-select fw-bold" required="" dmx-bind:value="prod_vars.data[variationIndex.value.toNumber()-1].var_id">
       <option value="" dmx-repeat:repeatvars="srvc_getVar_OptionList.data.query" dmx-bind:value="var_id" dmx-text="var_Name" dmx-bind:disabled="prod_vars.data.where(`var_id`, var_id, 'inArray')">option</option>
</select>

Which formatter should I use and how?
I have already tried ‘inArray’ , ‘contains’, ‘==’ but no luck… I don’t know if my syntax is wrong

I am talking about this solution that @mebeingken gave a few days ago on Paul’s question…

Disable an option in a form select when dynamic

Don’t add the dynamic options to the select element in the typical manner, instead add a single option element and add a repeat to the option. Then you can use dmx-bind:disabled. I did this with show/hide but should be the same for disabled.

How can I accomplish that in my case?
