Thanks for your comments Emipro Technologies.. You are right ... but the scenario is something different like as follows,

i have a field 

'f1': fields.selection([('1', '1'),('2', '2'),('3','3'),('4','4'),('5','5'),('6','6'),('7','7'),('8','8'),('9','9'),('10','10')], 'Communication Skills'),

similarly 11 more other fields like f2,f3, etc... and in my view.xml am making it like 

<group colspan="4" col="24">
     <field name="f1" widget="radio"/>
     <field name="f2" widget="radio"/>
      .
      .
</group>

The above alignment keep individual filelds in horizontal but the options in vertical order ..

So how do i align my selection options in horizontal ? 

Thanks...

horizontal radio button in odoo

Use your field f1 like this,

<field name="f1" widget='radio' options="{'horizontal': true}"/>

Hi Nishad,

You have to manage columns inside group to achieve your goal for manage 12 radio buttons horizontally. For ex.

<group colspan="4" col="24">
<field name="radio_field1" />
<field name="radio_field2" />
<field name="radio_field3" />
<field name="radio_field4" />
<field name="radio_field5" />
<field name="radio_field6" />
<field name="radio_field7" />
<field name="radio_field8" />
<field name="radio_field9" />
<field name="radio_field10" />
<field name="radio_field11" />
<field name="radio_field12" />
</group>

As above  colspan="4" means merge 4 columns, default Odoo seperated all group in 4 coulmns. And col="24" means create 24 columns after merge those 4 columns and all 12 radio button will fit inside it.

It may help a lot.

Update : 
You can manage as like below.

<group colspan="4" col="10">
    <field name="radio_field1" />
</group>
<group colspan="4" col="10">    
    <field name="radio_field2" />
</group>
 
...
...
<group colspan="4" col="10">
    <field name="radio_field12" />
</group>

I think you will get radio options as you want.
