how to view all items mat-select multiple

I'm using Angular Material and I would like to know if it is possible to automatically increase the size of mat-select when I select several security groups, because today when I select several, it can only visualize the groups that fit in the mat-select space. I wanted to be able to view all security groups.

Selected Groups - Mat-Select

HTML:

    <mat-form-field class="matfield"  appearance="outline" required>
      <mat-label>Secure Group</mat-label>
      <mat-select class="mat-select-securegroup" [formControl]="secureGroups" multiple>
        <mat-option *ngFor="let secureGroups of secureGroupsList" [value]="secureGroups"></mat-option>
      </mat-select>
    </mat-form-field>

COMPONENT.TS:

  secureGroups = new FormControl('');
  secureGroupsList: string[] = ['Secure Group 1', 'Secure Group 2', 'Secure Group 3', 'Secure Group 4', 'Secure Group 5', 'Secure Group 6'];

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
