Description

More of a documentation request than a feature request -- this is how to do a "controlled" (in the React parlance) version of a select tag:

const select = (options, value) =>
    yo`<select value="${value}">
        ${options.map((o) =>
            yo`<option value="${o.value}"
                ${value === o.value ? "selected" : ""}>
                ${o.label}
            </option>`
        )}
    </select>`

Note that you need to both set a value on the <select> tag and set the selected attribute on the selected <option>.

Contributor guide
