Hi Jaiti, this might be easier if you use a model on Opportunities. That way you can use a model condition for the Stage, you can use filter easily and you are still able to display all the Account information though the Opportunity. I created a simple page with standard objects and fields, hope this is helpful for you:

<skuidpage personalizationmode="server" showsidebar="false" useviewportmeta="true" showheader="false">
    <models>
        <model id="Opps" limit="20" query="true" createrowifnonefound="false" datasource="salesforce" sobject="Opportunity">
            <fields>
                <field id="RecordTypeId"/>
                <field id="AccountId"/>
                <field id="Account&#46;Name"/>
                <field id="StageName"/>
                <field id="Amount"/>
                <field id="Account&#46;Phone"/>
                <field id="Account&#46;CreatedDate"/>
            </fields>
            <conditions>
                <condition type="fieldvalue" value="Discovery" field="StageName" operator="=" enclosevalueinquotes="true"/>
                <condition type="fieldvalue" field="Amount" operator="gte" inactive="true" enclosevalueinquotes="false" name="__autofilter__nstart__Amount" state="filterableoff" value=""/>
                <condition type="fieldvalue" field="Amount" operator="lte" inactive="true" enclosevalueinquotes="false" name="__autofilter__nend__Amount" state="filterableoff" value=""/>

I also tried to use the model on Accounts. After you added “Opportunities” as Child Relationship field, you can apply conditions on it, e.g. “StageName = Discovery” and “Amount > 1000”.

So you will get a list of all Accounts, but you will only see filtered Opportunities. Is that the expected result? Please try the sample page below:

<skuidpage personalizationmode="server" showsidebar="false" useviewportmeta="true" showheader="false">
<models>
    <model id="Accounts" limit="20" query="true" createrowifnonefound="false" datasource="salesforce" sobject="Account">
        <fields>
            <field id="RecordTypeId"></field>
            <field id="Opportunities" type="childRelationship" limit="20">
                <fields>
                    <field id="Amount"></field>
                    <field id="StageName"></field>
                    <field id="Name"></field>
                </fields>
                <conditions>
                    <condition enclosevalueinquotes="true" operator="=" type="fieldvalue" field="StageName" value="Discovery"></condition>
                    <condition enclosevalueinquotes="false" operator="gt" type="fieldvalue" field="Amount" value="1000"></condition>
                </conditions>
            </field>
            <field id="Name"></field>
            <field id="Phone"></field>
            <field id="CreatedDate"></field>
        </fields>
        <conditions></conditions>
        <actions></actions>
    </model>
</models>
<components>
    <skootable showconditions="true" showsavecancel="true" showerrorsinline="true" searchmethod="server" searchbox="true" showexportbuttons="false" hideheader="false" hidefooter="false" pagesize="10" alwaysresetpagination="false" createrecords="true" model="Accounts" buttonposition="" mode="read" allowcolumnreordering="true" responsive="true" uniqueid="sk-3qJW-344" heading='Model on Account, Child relationship condition "StageName = Discovery" and "Amount > 1000"'>
        <fields>
            <field id="Name" uniqueid="fi-3qJW-347"></field>
            <field id="Phone" uniqueid="fi-3qJW-348"></field>
            <field id="CreatedDate" uniqueid="fi-3qJW-349"></field>
            <field id="Opportunities" type="CHILDREL" limit="100" uniqueid="fi-3qJW-346" allowhtml="true">
                <label>Opportunities</label>
                <template><b>Name: {{Name}}</b>

Stage: {{StageName}}

Amount: {{Amount}}

Thanks a lot Luzie.  I was able create a field on Oppty and filter. 

Great, thank you for the feedback!
