What is idm_frm attribute within html?

Question

I'm seeing an HTML attribute and I want to know more about it

I looked for answers in StackOverflow

<iframe src="NIB_MainFrame.asp" name="Principal" style="height:100%;width:100%;border:0;padding:0;border:0;margin:0;display:block;overflow-y:hidden" __idm_frm__="467"></iframe>`

I'm talking about the idm_frm attribute, sometimes I see it with the context of Selenium and I also saw idm_id

Any idea what it is?

It's not a standard attribute, however it is probably added by JavaScript, or in the very least used by JavaScript. — Greg Burghardt, Jun 13 '19 at 11:42
I'm really trying to find any documentation for what this means but can't seem to find. — Kprmn5555, Jun 13 '19 at 11:58
You probably won't find documentation on it, since it is a non standard HTML attribute and is likely used by a proprietary JavaScript library. — Greg Burghardt, Jun 13 '19 at 12:06

To start with Selenium itself doesn't add any tag or attribute within the HTML DOM.

By all possible means the attribute __idm_frm__="467" within the HTML, which is as follows:

<iframe src="NIB_MainFrame.asp" name="Principal" style="height:100%;width:100%;border:0;padding:0;border:0;margin:0;display:block;overflow-y:hidden" __idm_frm__="467"></iframe>`

looks to be dynamic and the attribute seems to be created/added by a JavaScript or AJAX.

As per the HTML in the question C#: Selenium - Element is not a frame element : FRAMESET it becomes much more clearer that the attribute is dynamically generated.

<iframe src="NIB_MainFrame.asp" name="Principal" style="height:100%;width:100%;border:0;padding:0;border:0;margin:0;display:block;overflow-y:hidden" __idm_frm__="467"></iframe>
<frameset id="frmSet" rows="55,0,*,24" border="0" framespacing="0" frameborder="no">
    <frame noresize="noresize" scrolling="no" name="Header" src="NIB_Header.asp" __idm_frm__="472">
    <frame noresize="noresize" scrolling="no" name="Menu" src="Blank.htm" __idm_frm__="473">
    <frame noresize="noresize" scrolling="auto" name="Corpo" src="NIB_Pre_Bridge.asp?txtAgencia=4346&amp;txtConta=014543708" __idm_frm__="474">
    <frame noresize="noresize" scrolling="no" name="Rodape" src="NIB_Rodape.asp" __idm_frm__="475">
</frameset>
</iframe>

An example of Ember.js enabled DOM Tree containing the __idm_frm__ attribute:

<section id="ember22904" class="ad-banner-container ember-view"><iframe class="ad-banner" width="496" height="80" src="about:blank" scrolling="no" title="advertisement" kwframeid="3" __idm_frm__="1347"></iframe>

An example of implementation in Facebook containing the __idm_frm__ attribute::

<iframe style="display: none;" __idm_frm__="21" id="IFRAME_1007"></iframe>

Conclusion

As the attribute __idm_frm__="xyz" does not contains a static value and dynamic in nature a wise decission would be to not to include this attribute while constructing any of the Locator Strategies.
