Opera
Per caniuse and personal testing, Opera has the same support for the
<summary>
element as it does for the<details>
element.Opera 52.0.2871.64 on OSX 10.11.6

Opera Mobile
Support per caniuse claims Opera Mobile has supported the
<details>
and<summary>
elements since version 37. Through personal testing, I can verify that the elements work at least with version 45, so I'm inclined to trust their claim.Links
