hx-select-oob

The hx-select-oob attribute allows you to select content from a response to be swapped in via an out-of-band swap.
The value of this attribute is comma separated list of elements to be swapped out of band. This attribute is almost always paired with hx-select.

Here is an example that selects a subset of the response content:

<div>
   <div id="alert"></div>
    <button hx-get="/info" 
            hx-select="#info-details" 
            hx-swap="outerHTML"
            hx-select-oob="#alert">
        Get Info!
    </button>
</div>

This button will issue a GET to /info and then select the element with the id info-detail, which will replace the entire button in the DOM, and, in addition, pick out an element with the id alert in the response and swap it in for div in the DOM with the same ID.
