# 📖 Rule Details

Limits the maximum number of attributes/directives per line to improve readability.

This rule aims to enforce a number of attributes per line in templates. It checks all the elements in a template and verifies that the number of attributes per line does not exceed the defined maximum. An attribute is considered to be in a new line when there is a line break between two attributes.

There is a configurable number of attributes that are acceptable in one-line case (default 1), as well as how many attributes are acceptable per line in multi-line case (default 1).

<script>
  /* eslint svelte/max-attributes-per-line: "error" */
</script>

<!-- ✓ GOOD -->
<input
  type="text"
  bind:value={text}
  {maxlength}
  {...attrs}
  readonly
  size="20"
/>
<button
  type="button"
  on:click={click}
  {maxlength}
  {...attrs}
  disabled
  data-my-data="foo"
/>

<!-- ✗ BAD -->
<input type="text" 
'bind:value' should be on a new line. (svelte/max-attributes-per-line)
bind:value={text} {maxlength} {...attrs} readonly />
<button type="button" 
'on:click' should be on a new line. (svelte/max-attributes-per-line)
on:click={click} {maxlength} {...attrs}> CLICK ME! </button>
