I have a multiple drop down list and I want to store the data into SQL Server Database when the user selects a particular option. The list is store in a JSON file and it is being displayed in the options in the drop down.
So if a person selects one drop down list the other list automatically displays a list based on the first one and so on. Upon clicking on submit button how can I store the selected values into a database.
Attaching a sample code for reference.
<table class="table">
    <thead>
        <th>
            Interaction Reason 1
        </th>
        <th>
            Interaction Reason 2
        </th>
        <th>
            Interaction Reason 3
        </th>
    </thead>
    <tbody>
        <tr>
            <td>
                <select name="IR1" id="IR1" class="form-control input-sm">
                    <option value=""></option>
                </select>
            </td>
            <td>
                <select name="IR2" id="IR2" class="form-control input-sm">
                    <option value="">--Select Option--</option>
                </select>
            </td>
            <td>
                <select name="IR3" id="IR3" class="form-control input-sm">
                    <option value="">--Select Option--</option>
                </select>
            </td>
        </tr>
    </tbody>
</table>
