bulk-actions

Handles bulk actions on list views — selecting items, enabling the execute button, and submitting the action form.

Attached to the root element via data-js-bulk-actions. Expects the following elements within root:

#bulk-action-form — the form to submit (omit if root itself is the form)
#bulk-select-all — checkbox to select/deselect all items
.bulk-select-item — per-row checkboxes (may be added dynamically via AJAX)
#bulk-action — select element listing available bulk actions
#bulk-action-execute — submit button, enabled only when items and an action are selected
[data-list-selection-count] — element displaying the number of selected items

Each <option> in #bulk-action may carry:

data-bulk-action — URL to set as the form action on submit
data-target — optional form target (e.g. _blank for PDF export in a new tab)
.bulk-confirmation-dialog + data-popup-title, data-popup-subject, data-popup-text — show a confirmation dialog before submitting

Uses event delegation on the root for .bulk-select-item changes so dynamically inserted rows (e.g. from async page tree loading) are handled without re-initialisation.
