Options

Gr4vy Embed can be configured in a few specific ways.

Element & Form

Gr4vy Embed expects the query for two HTML elements to attach itself to. The values for these elements are a query string that can be parsed by document.querySelector. For example, <div class="container" /> would be represented as .container, while <form id="cardform"> would be represented by #cardform.

HTML Element	Example	Description
element	.container	Specifies the HTML element to attach the form to. Gr4vy Embed will insert the form at this location. This parameter also supports directly providing a HTML element.
form	#order	Specifies the HTML <form> element or a query for the element to attach additional inputs to. Gr4vy will automatically insert a hidden Input field into this form containing the transaction ID.
