Asked On January 17, 2020 01:07 PM UTC

Hello everyone,,
I'd like to disable user interaction with the rule filter in the query filter, so that the user cannot select another filed from the list.
Say I have a query filter component as follow:
<ejs-querybuilder id="asQuerybuilder">
    <e-querybuilder-columns>
        <e-querybuilder-column label="Property1" field="Property1" type="string"></e-querybuilder-column>
        <e-querybuilder-column label="Property2" field="Property2" type="string"></e-querybuilder-column>
    </e-querybuilder-columns>
</ejs-querybuilder>

Once the control is rendered, the user can select the Property1 rule filter, and change the filed to Property2. I would like to disabled that.

Thanks !

Hi Humanjo,  
  
Thank you for contacting Syncfusion support.  
  
We have checked your requirement “Disable dropdownlist item in rule filter” and it can be achieved by adding custom class ‘e-disable’ to DropDownList using its ‘open’ event. Please check the below code example,  
  
<div class="col-lg-12 control-section"> 
    <ejs-querybuilder id="querybuilder" width="73%" rule="ViewBag.rule" dataSource="ViewBag.dataSource" maxGroupCount=5 created="createdControl" change="change"> 
        <e-querybuilder-columns> 
            <e-querybuilder-column field="EmployeeID" label="Employee ID" type="number"></e-querybuilder-column> 
            <e-querybuilder-column field="FirstName" label="First Name" type="string"></e-querybuilder-column> 
        </e-querybuilder-columns> 
    </ejs-querybuilder> 
</div> 
 
 
<script> 
    function createdControl() { 
        // Binding open event intially while creating the control 
        var ddlColl = document.querySelectorAll('.e-filter-input'); 
        for (var i = 0; i < ddlColl.length; i++) { 
            var ddl = ej.base.getComponent(ddlColl[i], "dropdownlist"); 
            ddl.open = Open 
        } 
    } 
    //Trigger before opening DropDownList 
    function Open() { 
        if (!this.popupObj.element.querySelectorAll(".e-list-item")[1].classList.contains("e-disable")) { 
            this.popupObj.element.querySelectorAll(".e-list-item")[1].classList.add("e-disable") 
        } 
    } 
    function change(args) { 
        if (args.type.indexOf('insert') > -1) { 
            // Binding open event while creating new rules 
            var qryBldrObj = ej.base.getComponent(document.getElementById("dropdownlist"), 'dropdownlist'); 
            var ddlColl = document.querySelector("#querybuilder_" + args.groupID).querySelectorAll('.e-filter-input'); 
            var ddl = ej.base.getComponent(ddlColl[ddlColl.length - 1], "dropdownlist"); 
            ddl.open = Open 
        } 
    } 
</script> 
 
<style> 
    .e-disable { 
        opacity: 0.6; 
        pointer-events: none; 
    } 
</style> 
 
  
  
For your convenience, we have prepared a sample based on your scenario and the same can be found in below link,
