# compose

I had prepared a AutoCompleteTextField few days ago but with the latest compose (alpha09) it seems like it's a bad idea to put a TextField inside a LazyColumn as one of its item, especially when its other items are decided based on what we type in the TextField, as I found my current implementation just gets stuck in an infinite loop of recomposition, freezing the textfield.

Any best practices, guidelines to follow in this regard? What should we keep inside a LazyColumn and what we shouldn't?

Why is the TextField inside the LazyColumn ?

[Kshitij Patil]

I was planning to show suggestions below it, so I thought I could use LazyColumn items for suggestion and use single item for TextField, as we use it for headers right now

[Dominaezzz]

Why not Column { TextField(....); LazyColumn { ... } } is what I'm getting at.

[Dominaezzz]

Or even better a DropdownMenu

[rsktash]

DropdownMenu is not good choice. Suggestions will be shown while we are typing based on the query. When drop-down shown input field loose focus automatically

[Dominaezzz]

That is configurable

[rsktash]

How can we configure?

[Dominaezzz]

We own the state of the composable. So we can keep in shown when we want.

expanded = true

[rsktash]

I’m not asking about visibility state. How can we prevent focus change of input field when dropdown shown ?

[Dominaezzz]

Ah I see. No idea, haven't used it much.

[Kshitij Patil]

I'm trying to implement a validator for AutoCompleteTextField (only items from a List are allowed) and I'm finding it really difficult. I hope it was available out of the box

[rsktash]

@Kshitij Patil Can you share the code?

[Adam Powell]

The issue in the OP of this thread sounds like a bug, please file it with an isolated repro if you have a few minutes. A text field inside of a LazyColumn should be alright.

[Kshitij Patil]

Now it sounds fishy to me as well because I remember it used to work in alpha07 , I'll try to create a repro when I get time and @rsktash you can also have a look at.
