For @patternfly/elements5.x, determine whether a slottedslot="icon"React child can render at the end ofpf-v5-buttoncontent, or whethericon-position only applies to the element's generated icon property.
💡 Result:
In @patternfly/elements 5.x, the pf-v5-button component handles icons primarily through the icon property/attribute, which provides a shorthand for rendering icons within the button [1][2]. While the component supports an icon slot for custom icon content, the icon-position attribute (or property) is specifically designed to control the positioning of the icon rendered via the icon property [1][3]. Regarding your specific questions: 1. Slotted icon content: You can use the icon slot to provide custom content (such as an or ) [1][2]. However, the icon-position property is intended to manage the layout of the icon set via the component's icon property, not necessarily to reorder arbitrary slotted elements [1][2]. If you place an element with slot="icon" inside the button, it will render, but the built-in icon-position logic may not automatically manipulate the position of that manual slot relative to your text content in the same way it manages the shorthand icon property [1][2]. 2. Scope of icon-position: The icon-position attribute applies to the icon specified by the component's icon property [1][3]. It determines whether that icon appears at the start (left) or end (right) of the button text [3]. For complex layouts or custom icon placement, it is often more predictable to manually order your elements within the button's default slot rather than relying on the component's shorthand icon management features [1].

@patternfly/elements 5.0.0 pf-v5-button source icon slot icon-position
💡 Result:
In @patternfly/elements version 5.0.0, the button component is named pf-v5-button [1][2]. The icon is managed via an icon attribute and an icon-position attribute, which determines where the icon appears in relation to the button text [3]. Key details for pf-v5-button icon management: Icon Attribute: You can define the icon using the icon attribute, which accepts the icon name (e.g., icon="arrow") [3]. This acts as a shorthand for placing an icon within the component [3]. Icon Position: The icon-position attribute is used to set the placement of the icon [3]. Supported values typically include "right" (defaulting to the end of the button content) [3]. Note on Styling: While the PatternFly core CSS uses logical modifiers such as.pf-m-start and.pf-m-end for positioning icons (where "start" and "end" are preferred over "left" and "right" for RTL/LTR support) [4][5][6], the @patternfly/elements pf-v5-button element abstracts this via its attributes [3]. Example usage: Label If you are migrating from older versions, note that all elements in version 5.0.0 now carry the pf-v5- prefix [2], and you should import them individually from @patternfly/elements/pf-v5-button/pf-v5-button.js [3][2].

🌐 Web query:
site:github.com/patternfly/patternfly-elements pf-v5-button icon-position slot="icon"
💡 Result:
In the PatternFly Elements library, the pf-v5-button component (part of the v5 element series) supports icons through property-based configuration rather than exclusively via a slot named "icon" [1][2]. While your query mentions icon-position slot="icon", standard usage for pf-v5-button involves using the icon attribute to specify the icon name [2]. For example: Search The component handles positioning and spacing automatically based on the button's content [3]. If you need to include custom elements or specific icon configurations that the simple attribute does not support, you may use standard slotting techniques if supported by the component's internal Shadow DOM template, though the primary API for icons is the icon attribute [2]. Please note that PatternFly Elements recently introduced a versioning scheme where components are prefixed with pf-v5- [4][5]. Ensure you are using the correct version imports (e.g., import '@patternfly/elements/pf-v5-button/pf-v5-button.js') as documented in the library [4].

Implement or reject trailing icon placement.
iconPosition="end" only changes the light-DOM child order. FeltButton does not pass icon-position to V5Button, and pf-v5-button renders its fixed icon slot before its text slot. The trailing-icon example therefore renders the icon before the label. Support trailing placement or warn for "end" and "right".
