editable.connectionTemplate String|Function

Specifies the connection editor template which shows up when editing the connection. A template can be used to change the default editors for the connection fields or to prevent some fields from being edited by not rendering an editor input for them.

Example - setting the connectionTemplate

<script id="popup-editor" type="text/x-kendo-template">
        <h3>Edit Connection Data</h3>
        <p>
        <label>From Shape: <input name="from" data-role="dropdownlist" data-bind="value: from" data-source="shapesDataSource" data-text-field="id" data-value-field="id" /></label>
  </p>
        <p>
        <label>To Shape: <input name="to" data-role="dropdownlist" data-bind="value: to" data-source="shapesDataSource" data-text-field="id" data-value-field="id" /></label>
  </p>
