Fastest: the search on your site in 5 minutes
- Sign in to your portal and open More → IDX widget (/portal/widget). If it is your first widget, click Create widget.
- Choose what to show (the whole Multilistado or only your listings), default filters and colors. The preview updates as you go.
- Copy the code and paste it into your site:
<script src="https://multilistado.mx/embed/w/YOUR-ID.js" async></script>
<div data-multilistado="search"></div>[multilistado_busqueda]<iframe src="https://multilistado.mx/embed/w/YOUR-ID" title="Property search" style="width:100%;min-height:900px;border:0" loading="lazy"></iframe>Replace YOUR-ID with your widget's 24-character ID. This is how it looks (live demo):
- Other agents' listings show their credit ("Listed by…") and inquiries come to you.
- Every showing requires the buyer to verify their ID (done on multilistado.mx, in a new tab).
