selection

A square control that turns one independent option on or off, used in sets where any number of the options may be chosen.

A select that accepts several values at once, usually showing the chosen ones as removable tokens inside the field.

A set of mutually exclusive options, each with its own label and control, exactly one of which can be chosen.

A radio or checkbox dressed as a card, where the whole tile is the target and the control itself is small or absent.

Two side by side lists with arrow buttons between them, used to move items from available to chosen and back.

Selecting several rows and applying one command to all of them, usually through a bar that appears once a selection exists and reports its count.

Offering to extend a selection from the visible page to every matching row, after a header checkbox has selected only what is on screen.

Dragging a selection across one chart to highlight the same records in every linked view.

Selecting by dragging a boundary around items on a canvas, freehand or as a rectangle, so whatever the outline encloses becomes the selection when the drag ends.

Choosing a contiguous run of items by marking one end and holding Shift while marking the other, selecting everything between them.

A widget where moving focus also selects, so arrowing through tabs or a listbox changes the selection immediately rather than on a second press.

The draggable grip at each end of a touch text selection, used to widen or narrow the range a finger cannot adjust precisely.

The animated dashed outline that circles a selection, moving continuously so the boundary reads as active rather than drawn.

The highlight painted behind text a reader has selected, which a page can restyle and thereby break the contrast the operating system had guaranteed.

A checkbox showing a third, indeterminate state when only some of the boxes it governs are checked.
