This article is about the Proxi admin app at app.proxi.co.
Many municipal sites run on CivicPlus (CivicEngage). Its Custom HTML widget takes the Proxi embed code as-is, and it's also happy with a plain iframe.
Steps on CivicPlus
In Proxi, copy the embed code (see Adding Proxi to Your Website: Which Code to Use).
Open the page in Live Edit, go to the Widgets tab, and drag a Custom HTML widget onto the page.
Paste the code, click Done, then Save. Accept the confirmation that you're adding custom code.
Good to Know
Try it on a copy of the page first. CivicPlus publishes on Save, and their own guidance is to test custom code on a duplicate page before touching a live one.
Some cities route all code changes through a web team. If you don't see Live Edit, send the embed code to whoever manages the site along with this article.
If your site runs on a different municipal CMS, look for a widget called HTML, Custom HTML, Embed, or Source. If none exists, the plain iframe or a link to your map always works.
