InlineStack

Deprecated

Product subscription app extensions won't be supported as of December 3, 2025. You should migrate existing product subscription app extensions to purchase options extensions.

Use to lay out a horizontal row of components.

A stack is made of flexible items that wrap each of the stack’s children. Options provide control of the alignment and spacing of the items in the stack. Use StackItem to group multiple elements inside a InlineStack together.

import {extend, InlineStack, Text} from '@shopify/admin-ui-extensions';

function buildStackText(root) {

const text = root.createComponent(Text);

text.appendChild('Items to stack');

return text;

}

extend('Playground', (root) => {

const inlineStack = root.createComponent(InlineStack, {

inlineAlignment: 'center',

spacing: 'loose',

});

inlineStack.appendChild(buildStackText(root));

root.appendChild(inlineStack);

root.mount();

});

import React from 'react';

import {extend, render, InlineStack, Text} from '@shopify/admin-ui-extensions-react';

function App() {

return (

<Text>Items to stack</Text>

</InlineStack>

);

}

extend(

'Playground',

render(() => <App />),

);

import {extend, InlineStack, Text} from '@shopify/admin-ui-extensions';

function buildStackText(root) {
  const text = root.createComponent(Text);
  text.appendChild('Items to stack');
  return text;
}

extend('Playground', (root) => {
  const inlineStack = root.createComponent(InlineStack, {
    inlineAlignment: 'center',
    spacing: 'loose',
  });

  inlineStack.appendChild(buildStackText(root));
  inlineStack.appendChild(buildStackText(root));
  inlineStack.appendChild(buildStackText(root));

  root.appendChild(inlineStack);

  root.mount();
});

import React from 'react';
import {extend, render, InlineStack, Text} from '@shopify/admin-ui-extensions-react';

function App() {
  return (
    <InlineStack inlineAlignment="center" spacing="loose">
      <Text>Items to stack</Text>
      <Text>Items to stack</Text>
      <Text>Items to stack</Text>
    </InlineStack>
  );
}

extend(
  'Playground',
  render(() => <App />),
);

optional = ?

Name	Type	Description
blockAlignment?	`"leading" \| "center" \| "trailing" \| "baseline"`	Specifies the block alignment. This affects the vertical flow of elements. Default value: `'leading'`
inlineAlignment?	`"leading" \| "center" \| "trailing"`	Specifies the inline alignment. This affects the horizontal flow of elements. Default value: `'leading'`
spacing?	`Spacing`	Adjust spacing between children. Default value: `'base'`

Anchor to GuidelinesGuidelines

All children of InlineStack are placed in a single view object, which makes recycling the views expensive and results in poorer performance when scrolling. Consider keeping your stacks simple.
By default, InlineStack alignment is 'leading’.

✅ Do	🛑 Don't
Keep Inline Stacks shallow. Complex hierarchies have performance penalties	Use complex and deep Stack layouts
