status
Another Database Table name under same database : company_policy
Under the database i have these columns:

<select id="bit_app_policy_category_parent" name="parent_id" class="form-control">
<option value=" {{"$parents->id"}} </option>n>
</select>
</div>
<div class="form-group">

Answer 1

First create two model
1. PolicyCategory and put the code in model
public function companyPolicies()
{
return $this->hasMany('App\CompanyPolicy');
}
2.CompanyPolicy
public function policyCategory()
{
return $this->belongsTo('App\PolicyCategory',policy_category_id);
}
and in you controller then you can get all the info of related table. Like say, you have one/two company under the policy_category which id is 1. Now you can get all the companies info like below
$policy_category = PolicyCategory::find(1);
dd($policy_category->companyPolicies);
try this and let me know is this really you want or not
