 > **Note**: There are some significant drawbacks to this approach. Both signals and memos need to own their values, so a memo will need to clone the field’s value on every change. The most natural way to manage state in a framework like Leptos is always to provide signals that are as locally-scoped and fine-grained as they can be, not to hoist everything up into global state. But when you _do_ need some kind of global state, `create_slice` can be a useful tool.

 Now, there’s a chance this all seems a little over-complicated, or maybe too restricted. I wanted to include actions here, alongside resources, as the missing piece of the puzzle. In a real Leptos app, you’ll actually most often use actions alongside server functions, [`create_server_action`](https://docs.rs/leptos/latest/leptos/fn.create_server_action.html), and the [`<ActionForm/>`](https://docs.rs/leptos_router/latest/leptos_router/fn.ActionForm.html) component to create really powerful progressively-enhanced forms. So if this primitive seems useless to you... Don’t worry! Maybe it will make sense later. (Or check out our [`todo_app_sqlite`](https://github.com/leptos-rs/leptos/blob/main/examples/todo_app_sqlite/src/todo.rs) example now.)

 You’ll notice that this version drops the `Submit` button. Instead, we add an `oninput` attribute to the input. Note that this is _not_ `on:input`, which would listen for the `input` event and run some Rust code. Without the colon, `oninput` is the plain HTML attribute. So the string is actually a JavaScript string. `this.form` gives us the form the input is attached to. `requestSubmit()` fires the `submit` event on the `<form>`, which is caught by `<Form/>` just as if we had clicked a `Submit` button. Now the form will “navigate” on every keystroke or input to keep the URL (and therefore the search) perfectly in sync with the user’s input as they type.
