EventBar UI component

Purpose

EventBar is a navigation/event/form component. Ordered event group. Use for related operations on rows, details, or results.

Inputs

Field	Required	Type	Behavior
`events`	yes	array	Ordered items. Each item requires `label` and exactly one of `onClick` or `href`.
`events[].label`	yes	string	Visible control text; must be non-empty.
`events[].onClick`	for emitted events	function	Go callback invoked when the item is activated.
`events[].href`	for links	safe URL/path	Same-origin paths, host-resolved resource URLs, or `https:` links allowed by the host external-link allowlist; invalid URLs fail validation. Mutually exclusive with `onClick`.
`events[].variant`	no	primary, secondary, danger, ghost	Default secondary; destructive uses danger.
`events[].disabled`	no	boolean	Default false; disabled items render but do not emit events.
`alignment`	no	start, end, between	Default `start`; `start` aligns the flat event list to inline start, `end` aligns it to inline end, and `between` spaces the flat list evenly across the row.
`density`	no	compact, normal	Default `normal`; `compact` reduces button gap and vertical padding for table rows or dense toolbars.

Boundary

Destructive events use the danger variant and must be backed by product-owned permission state. If confirmation is required, the product action carries that confirmation policy; if the user lacks permission, set events[].disabled: true or omit the entire event item instead of rendering an enabled control that will fail late.

Example

package reviewui

import (
  "github.com/busdk/bus-gx/pkg/gx"
  "github.com/busdk/bus-ui/pkg/ui"
)

func ReviewActions(approve func(), requestReview func()) gx.Node {
  return <EventBar events={[]ui.EventItem{
    {Label: "Approve", OnClick: approve, Variant: "primary"},
    {Label: "Request review", OnClick: requestReview},
  }}></EventBar>
}

Runtime Terms

Callback props documents function callback props.

Link targets must be same-origin paths or host-allowlisted https: URLs. Reject javascript:, data:, path traversal, and credential-bearing URLs.
