Then wherever you want the widget to appear on your page put the following in your HTML (you can use an element other than div if you like):
<div class="OCASI-211-search"/>
Change text and language:
There are 4 parameters you can set to override the default content of the widget; add these as data attributes on the OCASI-211-search element tag:
data-lang="fr" — will use French text values and link to locations in services.settlement.org/fr/
data-title="..." — will override the defautl title text
data-subtitle="..." — will override the text below the title
data-buttontext="..." — will override the text in the submit
Override styles (if you have access to CSS):
All the elements in the widget have style selectors that explicitly start with the .OCASI-211-search class, so you can selectively provide your own styles by targeting elements within that selector. Styles and class names will be visible in your browser's developer tools Elements panel, that should be your reference.
