If your sketch handles web pages, you can embed the pages into the AutoConnect menu in continuance enjoying the utility of the WiFi connection feature. Unlike the custom Web pages by [AutoConnectElements](acelements.md), this allows to legacy web pages registered by *ESP8266WebServer::on* or *WebServer::on* function.
You can use AutoConnectAux only constructed with the URI of the page to be embedding. AutoConnectElements is not required. The basic procedure for this as follows:
To implement embedding your legacy web pages to the AutoConnect menu, you can use AutoConnectAux only constructed with the URI of the page to be embedding. AutoConnectElements is not required. The basic procedure for this as follows:
1. Declare AutoConnectAux for each legacy page. It includes the URI of the page and item string which will display in the AutoConnect menu.

## <iclass="fa fa-question-circle"></i> Some AutoConnect page is cut off.
It may be two possibilities as follows:
1. Packet loss during transmission due to a too weak WiFi signal.
2. Heap is insufficient memory. AutoConnect entrusts HTML generation to PageBuilder that makes heavy use the String::concatenate function and causes memory fragmentation. This is a structural problem with PageBuilder, but it is difficult to solve immediately.
If this issue produces with your sketch, Reloading the page may recover.
Also, you can check the memory running out status by rebuilding the sketch with [PageBuilder's debug log option](faq.html#fn:2) turned on.
If the heap memory is insufficient, the following message is displayed on the serial console.

Is there the AutoConnectElements element named **SUBMIT** in the custom Web page? (case sensitive ignored) AutoConnect does not rely on the `input type=submit` element for the form submission and uses [HTML form element submit](https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/submit) function instead. So, the submit function will fail if there is an element named 'submit' in the form. You can not use **SUBMIT** as the element name of AutoConnectElements in a custom Web page that declares the AutoConnectSubmit element.
