I am having a problem implementing this ref with useRef. Can anyone guide me? @kabitacode ?

from react-native-material-menu.

@wilfriednhw hello! Right now you can create menus for each item, but this is not optimized. In the future, I will rework this library by using react context.

from react-native-material-menu.

Thank you for your answer, I have another problem.

for example, I have 6 elements, when I click on the first element, the menu is triggered on the sixth element.

What to do please

Does not work for me :(

@wilfriednhw i tried using ur solution but the problem of menu being displayed on the last item of flatlist is still there

from react-native-material-menu.

Same issue persisting for me . Did anyone found a solution for this ?

from react-native-material-menu.

in flatlist ( renderItem I added items and index)

showMenu = (item, index) => {
        this._menu[index].show()
    };

<Menu
  ref={(menu) => {this._menu[index] = menu}}
  button={<Text onPress={()=>this.showMenu(item, index)}>Show menu</Text>}>
  <MenuItem onPress={this.hideMenu}>Menu item 1</MenuItem>
  </Menu>

Solved for me :) thank's @jeffelector

from react-native-material-menu.

@Saad-Bashar same here

from react-native-material-menu.

showMenu = (item, index) => {
this._menu[index].show()
};

Solution worked for me:) thanks alots.

@Saad-Bashar same here

1. Create a variable inside your component let _menu : any = []
2. Inside your renderItem method and in Menu component pass this ref={(ref)=> _menu[index] = ref }
3. Open your Menu by calling _menu[index]?.show();
