How to get the object data related with the option selected in a search

I have a select tag with elements loaded from a DB. When I submit the form (search), I want to be able to show the selected value in an

tag. I am not using ajax and any django forms. I am just using plain html select tags inside form tag. I can show the Id but I don´t know how to get the other data (other fields).

My view:

    def filter(request):
        qs = StrategicObjective.objects.all()
        strategicplans = StrategicPlan.objects.all()
        strategicplan = request.GET.get('strategicplan')
        if strategicplan != 'Choose...':
            qs = qs.filter(strategicplan__id=strategicplan)
            qs = []
        return qs

    def filter_sec(request):
        qt = StrategicPlan.objects.all()
        strategicplan = request.GET.get('strategicplan')
        if strategicplan != 'Choose...':
            qt = strategicplan
            qt = []
        return qt

    def HomeView(request):
        qs = filter(request)   
        context = {
            'queryset': qs,
            'strategicplans': StrategicPlan.objects.all(),               
        return render(request, "home.html", context)

My template (the form part):

<div id="stratplan_search" class="container">
    <form class="form-inline" method="GET">
        <label class="my-1 mr-2" for="strategicplan">Strategic Plan</label>
        <select class="custom-select my-1 mr-sm-2" id="strategicplan" name="strategicplan">
            <option selected>Choose...</option>
            {% for stratplan in strategicplans %}
            <option value="{{ }}">{{ stratplan }}</option>
            {% endfor %}
        <button type="submit" class="btn btn-primary my-1">Submit</button>

And the template part where I want to show the data about the strategic plan selected (with this query I only have the Id):

    {% for strategicplan in queryset_sec %} 
    {% endfor %}
