Cyctoscape dash node movement

HI ,

is there a way to restrict the movement of a node towards y axis only in cyctoscape dash .

import dash
import dash_cytoscape as cyto
import dash_html_components as html

app = dash.Dash(__name__)

app.layout = html.Div([
    cyto.Cytoscape(
        id='cytoscape-two-nodes',
        layout={'name': 'preset'},
        style={'width': '100%', 'height': '400px','line-color': 'red'},
        elements=[
            {'data': {'id': 'one', 'label': 'Node 1'}, 'position': {'x': 75, 'y': 75}},
            {'data': {'id': 'two', 'label': 'Node 2'}, 'position': {'x': 200, 'y': 200}},
            {'data': {'source': 'one', 'target': 'two'}}
        ], 
        stylesheet=[
            {
            'selector': 'edge',
            'style': {
                'line-color': 'white'
            }
        }
        ]        
    ) 
]) 


if __name__ == "__main__":
   app.run_server( port = 8052, debug=True)

If I want the nodes to move only towards y axis . Can someone help .

Thanks,
Meera
