# SelectContent

Source: `client/lib/theme/vueda-tailwind/controls/index.js`

> The floating popover surface that holds the [SelectItem.root](/v3/reference/theming/keys/SelectItem.md#theme-key-SelectItem-root) options. Reads as a popover (2px radius, a hairline edge with popover elevation via `overlay-hairline`) capped at the viewport-available height that Reka exposes via `--reka-select-content-available-height`; the `popper`-position-only translate nudges (`translate-y-1`, etc.) sit the popover one 4px step off the trigger so the surface does not crash into the chip that opened it. The `item-aligned` legacy mode (the popover aligns itself to the selected item rather than anchoring to the trigger) skips those nudges and shares all other chrome.

Vue component: [SelectContent](/v3/reference/api/vue/SelectContent.md)

| Slot | Default classes | Description |
| --- | --- | --- |
| [root](/v3/reference/theming/keys/SelectContent.md#theme-key-SelectContent-root) | callback | The floating popover surface that holds the [SelectItem.root](/v3/reference/theming/keys/SelectItem.md#theme-key-SelectItem-root) options. Reads as a popover (2px radius, a hairline edge with popover elevation via `overlay-hairline`) capped at the viewport-available height that Reka exposes via `--reka-select-content-available-height`; the `popper`-position-only translate nudges (`translate-y-1`, etc.) sit the popover one 4px step off the trigger so the surface does not crash into the chip that opened it. The `item-aligned` legacy mode (the popover aligns itself to the selected item rather than anchoring to the trigger) skips those nudges and shares all other chrome. |
| [viewport](/v3/reference/theming/keys/SelectContent.md#theme-key-SelectContent-viewport) | callback | The padded inner region inside [SelectContent.root](/v3/reference/theming/keys/SelectContent.md#theme-key-SelectContent-root) that wraps the option list. In `popper` mode the viewport pins to the trigger's height and width (`--reka-select-trigger-height` / `--reka-select-trigger-width`) so the popover footprint matches the chip that opened it; `scroll-my-1` keeps the highlighted item from crashing into the viewport edge as keyboard navigation crosses long lists. The legacy `item-aligned` mode skips the pin and lets the viewport size to its content. |
