Uncollapse ThemedLayout sider

I'm using the antd <ThemedLayoutV2> component to render my app with a sider containing my navigation menu. When the sider is collapsed by clicking the '<' arrow, there isn't then a corresponding '>' arrow to un-collapse the sider. If I want to un-collapse it, I have to manually refresh the page. How can I configure the layout to handle collapsing and un-collapsing?

Hi @Hypnotic Meat. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To enable both collapsing and un-collapsing of the sider in the Ant Design <ThemedLayoutV2> component, you need to ensure that the sider's trigger (the arrow button) is visible and functional for both states. In the default <ThemedSider> implementation, the trigger should automatically switch between the '<' and '>' icons depending on the collapsed state. If you are not seeing the un-collapse ('>') arrow after collapsing, it may be due to a custom implementation or style override. The default behavior, as shown in the code example below, uses a trigger button that toggles the collapsed state:

<AntdLayout.Sider
  collapsible
  collapsedWidth={isMobile ? 0 : 80}
  collapsed={collapsed}
  breakpoint="lg"
  onCollapse={(collapsed: boolean): void => setCollapsed(collapsed)}
  trigger={
    !isMobile && (
      <Button
        type="text"
        style={{
          borderRadius: 0,
          height: "100%",
          width: "100%",
          backgroundColor: token.colorBgElevated,
        }}
      >
        {collapsed ? (
          <RightOutlined style={{ color: token.colorPrimary }} />
        ) : (
          <LeftOutlined style={{ color: token.colorPrimary }} />
        )}
      </Button>
    )
  }
>
  {/* ... */}
</AntdLayout.Sider>

<AntdLayout.Sider
  collapsible
  collapsedWidth={isMobile ? 0 : 80}
  collapsed={collapsed}
  breakpoint="lg"
  onCollapse={(collapsed: boolean): void => setCollapsed(collapsed)}
  trigger={
    !isMobile && (
      <Button
        type="text"
        style={{
          borderRadius: 0,
          height: "100%",
          width: "100%",
          backgroundColor: token.colorBgElevated,
        }}
      >
        {collapsed ? (
          <RightOutlined style={{ color: token.colorPrimary }} />
        ) : (
          <LeftOutlined style={{ color: token.colorPrimary }} />
        )}
      </Button>
    )
  }
>
  {/* ... */}
</AntdLayout.Sider>

This implementation ensures that when the sider is collapsed, a '>' (RightOutlined) icon appears, allowing users to un-collapse it. If you are using the default <ThemedSider>, this behavior should be present. If you have customized the sider or its trigger, make sure your custom code includes a similar toggle mechanism for both collapse and un-collapse actions. If you want to control the collapsed state programmatically or from elsewhere in your app, you can use the useThemedLayoutContext hook, which provides siderCollapsed and setSiderCollapsed for toggling the state:

const { siderCollapsed, setSiderCollapsed } = useThemedLayoutContext();

<Button type="primary" onClick={() => setSiderCollapsed(!siderCollapsed)}>
  Toggle collapse of sider
</Button>

const { siderCollapsed, setSiderCollapsed } = useThemedLayoutContext();

<Button type="primary" onClick={() => setSiderCollapsed(!siderCollapsed)}>
  Toggle collapse of sider
</Button>

This allows you to add custom buttons or triggers anywhere in your layout to control the sider's state collapse/uncollapse Sider component with useThemedLayoutContext hook. If you are still not seeing the un-collapse arrow, please check for any customizations or CSS that might be hiding the trigger, and ensure you are using the latest version of Refine and its Ant Design integration. Summary:
- The default <ThemedSider> should show both collapse and un-collapse arrows. - If customized, ensure your trigger logic handles both states. - You can also use useThemedLayoutContext to control the state programmatically. For more details and code examples, see the official documentation: collapse/uncollapse Sider component with useThemedLayoutContext hook. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
