我在Laravel Livewire项目中有一个表单，并尝试从数据库中搜索和选择用户。当我搜索用户然后搜索结果中的用户，但没有选择。此外，没有错误显示只是页面刷新。我的代码如下：我正在尝试这个

<div class="col-md-4">
    <div class="form-group row">
        <label class="control-label col-md-2 col-sm-2">Select User</label>
        <div class="col-md-10 col-sm-10 ">
            <div>
                <select wire:model="user_id" class="form-control" name="user_id" required>
                    <option></option>
                    @foreach($users as $user)
                        <option value="{{$user->id}}">{{$user->username}} : {{ $user->fullname }}</option>
                    @endforeach
                </select>
            </div>
            <div style="position:relative">
                <input wire:model.debounce.500ms="inputsearchuser" class="form-control relative" type="text"
                       placeholder="search..."/>
            </div>
            <div style="position:absolute; z-index:100">
                @if(strlen($inputsearchuser)>2)
                    @if(count($searchusers)>0)
                        <ul class="list-group">
                            @foreach($searchusers as $searchuser)
