# Background
Mobile sections are collapsed by default, but users can configure them to expand by default in mobile settings. The A/B test will expand all mobile sections regardless of user preference.
**Potential issue**: Logged-out users on the Minerva mobile site can toggle this setting. If our A/B test overrides their preference, it may skew results or create a confusing user experience for those who deliberately chose collapsed sections.
Below is a screenshot of the mobile settings (Minerva mobile + mobile emulation):

The clientpref selectors are defined in MobileFrontend extension ([ref](https://codesearch.wmcloud.org/search/?q=mf-expand-sections-clientpref&files=&excludeFiles=&repos=)) and added to the <html> element.
- `mf-expand-sections-clientpref-0` collapses the sections by default
- `mf-expand-sections-clientpref-1` expands the sections by default
## Acceptance Criteria
[x] Determine whether the user configurations conflict with the A/B test ([details](https://phabricator.wikimedia.org/T409485#11368497))
[x] Document findings and next steps, including an approach to disable the user settings if needed
## Notes
- Based on these [findings](https://phabricator.wikimedia.org/T409485#11368497), the user settings do not conflict with the prototypes' expanded section behavior.
- Future implementation options:
- Option 1: Do nothing
- Option 2: Disable the setting if enrolled in the experiment
