Hi @lukevo.. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- I'm sorry, but your question seems incomplete. If you're asking about how to customize or use the Sider component in refine, I can certainly help with that. Refine uses the Ant Design Sider component by default. The default sidebar can be customized by using refine hooks and passing custom components to the Sider property. You can create your own Sider Menu with refine quite simply. Here's an example of how to create a custom Sider with role-based menu items:

import { useCan } from "@refinedev/core";
import { Menu } from "@refinedev/antd";

const CustomSider = () => {
  const canViewMenuItem1 = useCan({ resource: "menuItem1", action: "view" });
  const canViewMenuItem2 = useCan({ resource: "menuItem2", action: "view" });

  return (
    <Menu>
      {canViewMenuItem1 && <Menu.Item key="menuItem1">Menu Item 1</Menu.Item>}
      {canViewMenuItem2 && <Menu.Item key="menuItem2">Menu Item 2</Menu.Item>}
    </Menu>
  );
};

import { useCan } from "@refinedev/core";
import { Menu } from "@refinedev/antd";

const CustomSider = () => {
  const canViewMenuItem1 = useCan({ resource: "menuItem1", action: "view" });
  const canViewMenuItem2 = useCan({ resource: "menuItem2", action: "view" });

  return (
    <Menu>
      {canViewMenuItem1 && <Menu.Item key="menuItem1">Menu Item 1</Menu.Item>}
      {canViewMenuItem2 && <Menu.Item key="menuItem2">Menu Item 2</Menu.Item>}
    </Menu>
  );
};

Then, pass the CustomSider component to the Layout component's Sider property:

import { Layout } from "@refinedev/core";
import CustomSider from "./CustomSider";

const App = () => {
  return (
    <Layout Sider={CustomSider}>
      {/* Your app content */}
    </Layout>
  );
};

import { Layout } from "@refinedev/core";
import CustomSider from "./CustomSider";

const App = () => {
  return (
    <Layout Sider={CustomSider}>
      {/* Your app content */}
    </Layout>
  );
};

For more information, refer to the useMenu hook documentation (https://refine.dev/docs/api-reference/core/hooks/ui/useMenu/). If you're asking about something else, could you please provide more details? ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you. One moment! :books: ---------------------- I'm sorry, but the information provided in the extracts does not contain a solution to the circular reference error you're encountering. The error typically occurs when there's a circular structure in a JavaScript object which JSON.stringify() is not capable of handling. However, based on the code snippet you've provided, I don't see any obvious circular references. The customMenuItems array contains an object with a children property, which is another array of objects, but this is a common pattern and shouldn't cause a circular reference error. If you're trying to stringify this object using JSON.stringify(), it should work without any issues. If you're still encountering this error, the issue might be elsewhere in your code. If you're using refine and trying to create a nested menu, you might want to refer to the refine documentation (https://refine.dev/docs) or ask for help in the refine Discord community (https://discord.com/channels/837692625737613362/1121423983812812810). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai This is my code import React, { useMemo } from "react"; import { ThemedLayoutContextProvider } from "@refinedev/antd"; import { ThemedHeaderV2 as DefaultHeader } from "./header"; import { ThemedSiderV2 as DefaultSider } from "./sider"; import { Grid, Layout as AntdLayout } from "antd"; import type { RefineThemedLayoutV2Props } from "@refinedev/antd"; export const ThemedLayoutV2: React.FC<RefineThemedLayoutV2Props> = ({ children, Header, Sider, Title, Footer, OffLayoutArea, initialSiderCollapsed, }) => { const breakpoint = Grid.useBreakpoint(); const SiderToRender = Sider ?? DefaultSider; const HeaderToRender = Header ?? DefaultHeader; const isSmall = typeof breakpoint.sm === "undefined" ? true : breakpoint.sm; const hasSider = !!SiderToRender({ Title }); return ( <ThemedLayoutContextProvider initialSiderCollapsed={initialSiderCollapsed}> <AntdLayout style={{ minHeight: "100vh" }} hasSider={hasSider}> <SiderToRender Title={Title} /> <AntdLayout> <HeaderToRender /> <AntdLayout.Content> <div style={{ minHeight: 360, padding: isSmall ? 24 : 12, }} > {children} </div> {OffLayoutArea && <OffLayoutArea />} </AntdLayout.Content> {Footer && <Footer />} </AntdLayout> </AntdLayout> </ThemedLayoutContextProvider> ); }; Circular Reference Error

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the provided code and the information from the extracts, it's not clear why you're encountering a circular reference error. The code you've shared doesn't seem to have any circular references. However, a circular reference error typically occurs when you're trying to stringify an object that has a circular structure. For example, if an object references itself, or two objects reference each other, trying to stringify them with JSON.stringify() will result in a circular reference error. If you're encountering this error in the context of using JSON.stringify(), you might want to check the objects you're trying to stringify. If you're not using JSON.stringify(), the error might be coming from somewhere else in your code. Unfortunately, without more context or a more detailed error message, it's hard to provide a more specific solution. If you're using refine and this error is related to it, you might want to refer to the refine documentation (https://refine.dev/docs) or ask for help in the refine Discord community (https://discord.com/channels/837692625737613362/1121423983812812810). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Uncaught RangeError: Maximum call stack size exceeded. I have debugged this and it's at the parent. How to fix?

message.txt

kapa.ai•9mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The "Maximum call stack size exceeded" error typically occurs when there's a recursive call with no exit condition, causing the stack to overflow. This can happen if a function keeps calling itself, or if two functions call each other, without a condition to stop the recursion. Based on the information provided in the extracts, it's not clear where exactly in your code this error is occurring. However, you mentioned that it's at the "parent". If this refers to a parent component in a React application, you might want to check if there's any unintentional recursion happening in that component or its children. Here are a few things you can check: 1. Look for any recursive function calls or component renderings in your parent component. Make sure there's a condition that stops the recursion. 2. Check if there's any state or prop updates that are causing an infinite loop of re-renders. 3. If you're using hooks, make sure you're not causing an infinite loop with useEffect. If you're passing a prop or state value to the dependency array of useEffect, and then updating that value inside useEffect, it could cause an infinite loop. If you're using refine, and this error is related to it, you might want to refer to the refine documentation (https://refine.dev/docs) or ask for help in the refine Discord community (https://discord.com/channels/837692625737613362/1121423983812812810). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
