[SalesForce] How to display List> in Visual force page

Your query is looking for an exact match. ie where the FirstName includes John, Dan and Nancy. If you wanted to search for records that have one or more of those values set then try this:

Select FirstName From Contact Where FirstName Includes ('John', 'Dan', 'Nancy')

You could also use a List, as shown here:

List<String> s = new List<String>{'John', 'Dan', 'Nancy'};
Select FirstName From Contact Where FirstName Includes (:s)

See here for more information

You should be able to use the <apex:repeat> tag to display your list values. From the help docs here, here is an example:

For this example to render properly, you must associate the Visualforce page

with a valid account record in the URL.

For example, if 001D000000IRt53 is the account ID, the resulting URL should be:

https://Salesforce_instance/apex/myPage?id=001D000000IRt53

See the Visualforce Developer's Guide Quick Start Tutorial for more information.

<!-- Page: -->

<apex:page standardController="Account">

    <table border="0" >

        <tr>

            <th>Case Number</th><th>Origin</th>

            <th>Creator Email</th><th>Status</th>

        </tr>

        <apex:repeat var="cases" value="{!Account.Cases}">

        <tr>

            <td>{!cases.CaseNumber}</td>

            <td>{!cases.Origin}</td>

            <td>{!cases.Contact.email}</td>

            <td>{!cases.Status}</td>

        </tr>

        </apex:repeat> 

    </table>

</apex:page>

Update: Try swapping out the variables in the above example with your list and values. Something like this should work:

<!-- Page: -->

<apex:page standardController="Your standard or custom object here">

    <table border="0" >

        <tr>

            <th>Sub Type</th>

        </tr>

        <apex:repeat var="ten" value="{!generalList}">

        <tr>

            <td>{!gen.Sub_Type__c}</td>

        </tr>

        </apex:repeat> 

    </table>

</apex:page>
