Walkthrough

The ticket-type input now renders its menu in a portal attached to document.body. The portal menu uses a z-index of 1400. The Input import also gains a semicolon.

Changes: Ticket type menu

Portal the ticket-type menu

The ticket-type input renders its menu in document.body and sets the portal menu z-index to 1400. The Input import gains a semicolon.

Estimated code review effort: 2 (Simple) | ~5 minutes

Merge Risk: Low · up to da0c8

The change raises the ticket-type dropdown above other content and keeps bulk editor menus inline. A few other selects in scrolling containers could still show menus that do not follow their controls. This is a minor visual risk and does not block merge.

Explanation

The title names the fix (z-index for the ticket type dropdown on the ticket form), which matches the objectives and the summarized changes. The changeset also touches bulk editor components by setting menuPortalTarget to null, but the title does not need to cover every detail. The title is concise, specific, and follows the conventional prefix style.

@tomrndom With the global menuPortalTarget, a react-select near the bottom of a react-bootstrap Modal now opens its menu on top of its own control and scrolls the page behind the modal.

react-select 2.4.4 picks the scroll container from where the menu sits in the DOM (getScrollParent → getMenuPlacement). Inline, the menu sits inside .modal, which Bootstrap 3 makes the scroll container (.modal-open .modal { overflow-y: auto }). When the menu doesn't fit below the control, react-select scrolls the modal and the menu stays attached; that is the behavior on master. Once the menu is portaled under <body>, the scroll container becomes documentElement. react-select then calls animatedScrollTo on the page behind the fixed modal; the overflow: hidden that react-overlays puts on the body doesn't block that. The control stays where it is and the menu moves up by the scroll amount.

I reproduced it with react-select 2.4.4 and the Bootstrap 3.3.7 modal rules, with a select 17px above the viewport bottom:

  • inline (master): the modal scrolled 291px and the menu opened 8px below the control
  • with this patch: the page behind the modal scrolled 299px and the menu ended up 291px above the control's bottom edge, covering it

It happens on every open, without the user scrolling, and the list page stays scrolled after the modal closes. Options remain selectable, so it's cosmetic. One likely place to hit it is the "send emails" modal in summit-speakers-list-page.js: the TagInput / BadgeFeatureInput / TicketTypesInput rows from SpeakerPromoCodeSpecForm sit low in it.

Suggested fix: for selects rendered inside a modal, add menuPosition="fixed", matching what admin-access-form.js and the events grid filters (summit-event-list-page/helpers.js) already do with a portaled menu. With fixed, react-select places the menu in viewport coordinates and flips it above the control instead of scrolling the document. In the same repro it opened above the control with no page scroll.

I'd avoid making menuPosition: "fixed" a global default here. On regular pages an open fixed menu doesn't follow the control when the page is scrolled. It would also bring back the bulk-editor issue, because menuPortalTarget={null} with fixed still renders through MenuPortal. If you'd rather keep this PR as the temporary global fix, documenting it as a known limitation for the legacy modals is fine too.

🟡 Changes recommended

The global select portal is hidden from the accessibility tree when a MUI dialog opens, making dialog select menus inaccessible to assistive technology.
