<h3>Using "allowCode"</h3>
|
|
|
105 |
|
|
|
106 |
<div class="box label">
|
|
|
107 |
<b>Note:</b> The allowCode feature is powerful, but leads to poor separation of concerns, and poor maintainability.
|
|
|
108 |
<br />It is therefore only available as an opt-in feature on a per template basis.
|
|
|
109 |
<br /><br />The following two examples illustrate its use, but are not the recommended approach. The built-in expression support,
|
|
|
110 |
<br />custom tags, helper functions etc. provide a better solution for almost all scenarios, as in the two examples above.</div>
